How To Choose Pipe Materials for Home Repiping
Pipes are vital to a healthy home. They bring fresh water inside, fueling modern conveniences like the shower, dishwasher, and sprinkler system. More importantly, they direct sewage and dirty water out.
But over time, pipes need maintenance and replacement. There are two main materials for piping used in homes, PEX and copper. How do homeowners know which one to use? This article covers the basics and helps inform those on the market for pipe replacement.
Examining the Differences Between Pex and Copper Pipes
Copper is the old standby for plumbing in homes; it’s been used as far back as ancient Egypt. PEX, or cross-linked polyethylene, is the newcomer on the block. The material has only been around since the 1960s. The main difference between copper and the newer PEX material is that copper is metal and PEX is a flexible polyurethane. Both materials are solid choices for plumbing needs, but each has its pros and cons.
Considering PEX Pipes
PEX pipes, while a newer technology, has picked up steam over the years. A budget-conscious homebuyer should take a look at the flexible pipe option for any of their plumbing updates.
Pros of PEX Pipes
- Economical: PEX runs cheaper by copper. The material does not need fitted or cut to size as often as copper, saving money on the plumbing bill.
- Easy Install: For those that are handy and don’t mind a little DIY, PEX pipes can be done without help. Since the pipes are flexible and easily navigate around fixtures, the pipes are easier and faster to install than copper pipes.
- Fewer Connections to Worry About: PEX is a flexible material that can wrap around corners and snake around any home obstructions. It runs continuously from a water-distribution panel to each fixture (tub, sink, etc.)
- PEX Controls Are Centrally Located: PEX pipe is installed with each pipe connected to the water-distribution manifold near the house's water main. This acts as a hub where each pipe has its shutoff valve on the manifold.
Cons of PEX Pipes
- Shorter Lifespan: PEX pipes last about 30 to 50 years, about 20 years fewer than copper piping.
- DIY Is Not Always Possible: City ordinances may not allow DIY installation in homes. Be sure to research and follow all building codes in the area.
- Not as Tough as Copper: PEX pipes are susceptible to high-heat and chemicals. Both exposures can result in the breaking down of the pipes.
- Not Antibacterial: PEX is not antibacterial and can spread waterborne bacteria if contaminated.
Considering Copper Pipes
Copper pipes are arguably one of the oldest materials used for piping in the world. There’s a reason they’ve been used for so long: they’re reliable and sturdy. They’re a great choice for almost any piping needs.
Pros of Copper Pipes
- Corrosion-Resistant: Copper is a naturally corrosion-resistant material. They do not break down as easily as galvanized steel and are less susceptible to rust than other metals.
- Lightweight: Copper is a light material to work with. It is easily installed without support across longer distances.
- Environmentally Friendly: Copper is a naturally occurring material and does not produce toxic fumes when constructed.
- Antibacterial: Copper is naturally antibacterial. It inhibits the growth of waterborne bacteria, keeping the water source cleaner.
- Lasts Longer Than PEX: Copper pipes can last up to 70 years and are a sturdy option for piping.
Cons of Copper Pipes
- Expensive Option: Copper pipes may cost less than steel, but they cost about twice that of PEX pipes.
- Susceptible to Acidic Water: Well-water is not a friend to copper pipe. Highly acidic water can strip iron and copper from the pipes. This can leave a blue copper residue on plumbing fixtures. This erosion leads to pinhole leaks in the pipe.
- Time Consuming Installation: Copper pipes need more fixtures than PEX pipes.
- May Require Demolition: Furthermore, installing copper may need drilling through walls to install the new piping. Replacing dry-wall is not a task performed by plumbers. Dry-wall replacement often requires another professional to install it.
When it comes to picking the right piping for the home, PEX and copper are both great options to consider. Reach out to a local plumber for more information on what pipes are best.
